Remarks of President Barack Obama: Acceptance of the Nobel Peace Prize

Let me also say this: the promotion of human rights cannot be about exhortation alone. At times, it must be coupled with painstaking diplomacy. I know that engagement with repressive regimes lacks the satisfying purity of indignation. But I also know that sanctions without outreach  and condemnation without discussion  can carry forward a crippling status quo. No repressive regime can move down a new path unless it has the choice of an open door.

In light of the Cultural Revolution's horrors, Nixon's meeting with Mao appeared inexcusable  and yet it surely helped set China on a path where millions of its citizens have been lifted from poverty, and connected to open societies. Pope John Paul's engagement with Poland created space not just for the Catholic Church, but for labor leaders like Lech Walesa. Ronald Reagan's efforts on arms control and embrace of perestroika not only improved relations with the Soviet Union, but empowered dissidents throughout Eastern Europe. There is no simple formula here. But we must try as best we can to balance isolation and engagement; pressure and incentives, so that human rights and dignity are advanced over time. (See pictures "Fun with Photoshop: Obama's Other Awards.")

Third, a just peace includes not only civil and political rights  it must encompass economic security and opportunity. For true peace is not just freedom from fear, but freedom from want.

It is undoubtedly true that development rarely takes root without security; it is also true that security does not exist where human beings do not have access to enough food, or clean water, or the medicine they need to survive. It does not exist where children cannot aspire to a decent education or a job that supports a family. The absence of hope can rot a society from within. (See pictures from Obama's first state dinner.)

And that is why helping farmers feed their own people  or nations educate their children and care for the sick  is not mere charity. It is also why the world must come together to confront climate change. There is little scientific dispute that if we do nothing, we will face more drought, famine and mass displacement that will fuel more conflict for decades. For this reason, it is not merely scientists and activists who call for swift and forceful action  it is military leaders in my country and others who understand that our common security hangs in the balance.

Agreements among nations. Strong institutions. Support for human rights. Investments in development. All of these are vital ingredients in bringing about the evolution that President Kennedy spoke about. And yet, I do not believe that we will have the will, or the staying power, to complete this work without something more  and that is the continued expansion of our moral imagination; an insistence that there is something irreducible that we all share.

As the world grows smaller, you might think it would be easier for human beings to recognize how similar we are; to understand that we all basically want the same things; that we all hope for the chance to live out our lives with some measure of happiness and fulfillment for ourselves and our families.

And yet, given the dizzying pace of globalization, and the cultural leveling of modernity, it should come as no surprise that people fear the loss of what they cherish about their particular identities  their race, their tribe, and perhaps most powerfully their religion. In some places, this fear has led to conflict. At times, it even feels like we are moving backwards. We see it in Middle East, as the conflict between Arabs and Jews seems to harden. We see it in nations that are torn asunder by tribal lines.

Most dangerously, we see it in the way that religion is used to justify the murder of innocents by those who have distorted and defiled the great religion of Islam, and who attacked my country from Afghanistan. These extremists are not the first to kill in the name of God; the cruelties of the Crusades are amply recorded. But they remind us that no Holy War can ever be a just war. For if you truly believe that you are carrying out divine will, then there is no need for restraint  no need to spare the pregnant mother, or the medic, or even a person of one's own faith. Such a warped view of religion is not just incompatible with the concept of peace, but the purpose of faith  for the one rule that lies at the heart of every major religion is that we do unto others as we would have them do unto us.

Adhering to this law of love has always been the core struggle of human nature. We are fallible. We make mistakes, and fall victim to the temptations of pride, and power, and sometimes evil. Even those of us with the best intentions will at times fail to right the wrongs before us.
